When stopping a keygrabber with a timeout manually or through the stop
key, the timer would continue and call the stop callback again some time
later.
The error message in `gears.timer:stop` is removed, since there actually
is no harm in just returning immediately. And the timer implementation
itself calls `:stop` in certain places without checking for `.started`,
which lead to a situation where the internal call to `stop` triggered
the error message.

Currently, emit_signal always call all connected function. However,
it is very wasteful for some I/O intensive operations like icon
lookup. This commit adds a trick (private API) to stop once
a condition is met.
It will also in the future be used for the permission system, but
this is not yet implementd.
Having the new object layout will be important soon when the
append/remove methods start to get added to the client and the
reborn `awful.keyboard` module.
The `:keys()` and `:buttons()` APIs moved from get/set single methods
to properties. It works fine if you use the new or old API, but has
limitations when mixing them. `awful.rules` calls properties in a loop
after checking if it is a function. Thus it triggers the secondary
codepath to try to handle this case.
This codepath was tested with gears.objects based components
(ie. widgets). It was not tested with clients and tags, and it
didn't work because they use `awful.tag.getproperty` and
`awful.client.property.get` instead of `._private` like all
newer components. Those old functions are officially deprecated,
but used by tons of configs and modules ported from v3.5 and thus
still the default way to access Lua properties in our implementation.
This commit adds a `_private` to anything that doesn't have one to
at least make the error stop. It will "mostly" work until a more
complete solution is added. Reverting the 2 PRs that changed this
would delay getting more feedbacks.
Many legacy Awesome APIs such as `client:tags()`, `root.buttons()`,
`client:keys()`, `drawin:geometry()`, etc used functions for both the getter
and setter. This contrast with just about everything else that came after
it and is an artifact of an earlier time before we had "good" Lua object
support.
Because both consistency and backward compatibility are important, this
table wrapper allows to support both the legacy method based accessors
and key/value based accessors.
It isn't part of the public API, has a sledgehammer function prototype
and is intended for internal use only.
It's ugly, but backward compatibility is more important than anything
else.
